< Topic >Being the device which prevents the damage to the farm products and the fruit tree by the Aves, receiving the natural wind, it offers the kazaguruma device which does not have the fact that it declines the precaution of Aves such as bulbul and crow by irregular moving always it turns not only, direction of the wind, regardless of the breeze, it turns over the long period of time.SolutionsFalcon existence of predatory birds is made to recognize such as 1 photographs of predatory birds such as the aluminum foil which reflects the sunlight on the surface of feather 1 of rotary possible kazaguruma which is exposed in the atmosphere and the falcon which is the natural enemy of the wild bird Aves or multiple installation and bulbul such as that visible light and by receiving the reflected light of the ultraviolet ray. With rotary possible 2 rotary shafting 5, direction of the wind, regardless of wind velocity, the feather of kazaguruma turns even to perpendicular direction with the axis where kazaguruma turns tries to become rockable.< Choice figure >Drawing 1【課題】鳥類による農作物、果樹への被害を防止する装置であって、自然の風を受けて回転するだけでなく、風の方向、微風にかかわらず、常に不規則な動き、回転をすることにより長期間に渡ってもヒヨドリ、カラス等の鳥類の警戒心を減退させることのないカザグルマ装置を提供する。【解決手段】大気中に露出した回転可能なカザグルマの羽根1の表面に太陽光線を反射するアルミ箔や野鳥の天敵であるハヤブサ等猛禽類の写真を1個もしくは複数個取り付け、ヒヨドリ等の鳥類がその可視光線や紫外線の反射光を受けることによりハヤブサ等の猛禽類の存在を認識させる。カザグルマの回転する軸と直角方向にも回転可能な2個の回転軸系5を持ち、風の方向、風速にかかわらずカザグルマの羽根が回転、揺動可能となるようにする。【選択図】図1
